ROYALOHM resistors Royal Ohm specialize in designing, and producing resistors, which are passive electronic components used to restrict the flow of electric current in a circuit. Resistors are essential components in nearly all electronic devices and systems, ranging from consumer electronics to industrial machinery and aerospace applications. These components come in various types, including fixed resistors, variable resistors, and specialty resistors.

Royal Ohm manufacturers a wide range of resistor types to suit different applications. Some common types include carbon film resistors, metal film resistors, wirewound resistors, thick film resistors, and thin film resistors.

IBS Electronics is a global distributor of high quality electronic components, including RoyalOhm. We operate a seamless global network in offices in Asia, Europe, and the Americas, and can ship RoyalOhm resistors to any part of the world.
